Second, if you are bluffing people and simply cheating money, don't worry, don't tell everyone what the school is like. After all, that's where I work. Respect for the past means respect for yourself. Of course, if friends and relatives go, you can give some advice.
Third, if you are really teaching something. Then you can choose your target customers and need to be recommended by people from this school. You can make money and help others, so why not?
As for your training method, it's just a matter of work style. Don't care too much.
I hope I can help you.
